fuel pump was happy, after the pressure was eased , the pump is extremely quiet, no more whine[8D], feels like I gained ALOT of power now,3500-6000 rpm gets scary

GTDaniel: I had a 1990 Mustang that did the flickering light thing.
Everything always checked out.
It ended up being the wire going to the right bank Oxy Sensor.
When you went around a corner it would lay against the hot exhaust and burn through the ins. creating a bare spot.
Then everytime it touched after that the light came on.
May not be your problem but it's cheap to take a look.

Did you set it to 45 with or without the vaccum connected? Is the ambient air temperature sensor the same as the air charge temperature sensor?

Same sensor, driver side, front on the intake lower manifold.

An adjustablefuel pressureregulator has no vacum line, so plug your old line with a piece of paper.

I understand fuel pressure guages are expensive, however you can borrow mine with the correct adapter on it for
$10.00 paypal shipped to anyone in USA, and you pay for return shipping of like only $5.00 back to me.


Put the regulator on first, which requires removal of the passeneger side fuel rail and injector connectors, 8mm bolts(2).
and a allen key for the regulator bolts.


25 min procedure
